Sears offers the Skechers Girls' Halogen Shoes in White for $13.75 plus $6.99 for shipping. (Alternatively, orders of $25 or more get free shipping.) That's the lowest total price we could find by $4. Sales tax is added where applicable. They come in toddler/youth sizes from 11 to 13 and youth sizes 1 to 3.
Update: We've corrected the shipping on this deal; in-store pickup is not available.
